Title: Spherical microwave lens
Inventor: PETERS BASIL
IPC: H01Q15/08
Filed: 1961-10-03
Abstract: 947,238. Microwave lenses. FAIREY ENGINEERING Ltd. Oct. 2, 1962 [Oct. 3, 1961; Dec. 15, 1961], Nos. 35699/61 and 45090/61. Drawings to Specification. Heading H4A. The invention relates to the design and manufacture of spherical microwave lenses comprising a number of spherical or part spherical shells fitting one within the other, the shells having respective dielectric constants such that radio waves incident upon the lens are brought to a focus and reflected preferably back along the incident path. Charts A-D (not shown) disclose design parameters and are described with reference to a proposed lens (not shown) comprising a centre sphere of diameter " dc " of 2.5 inches and eight shells of equal thickness " ts " of 0.5 inch such that the overall diameter " dR " of the lens is equal to 10.5 inches. From this data the shell thickness ratio ts/dR= 0.0476 and the centre sphere ratio dc/dR= 0.238 are calculated. A line is drawn parallel to the vertical dielectric constant axis on each of charts A-D at an abscissal value of 0.0476 and the values at which these lines cut the chart curves are transferred to Fig. 5 to give four sets of vertically aligned points. Corresponding points are joined and a vertical line corresponding to the required centre sphere ratio is added. The required dielectric constants of the centre sphere and the surrounding shells are given by the points of intersection between this vertical line and the derived curves. Graphs A-E (not shown) disclose the dielectric constants for five specific lenses given as examples and show how these dielectric constants differ from those determined by previously known techniques. Each shell is moulded from expanded polystyrene which is preheated before moulding, some of the shells containing titanium dioxide. A part-spherical metal reflector may be applied to the outer surface of the finished lens.

Title: Improvements in or relating to pneumatic conveyor apparatus for feeding aggregates
IPC: B65G53/00
Filed: 1938-12-07
Abstract: 522,391. Pneumatic conveyers. McCURDY, S. L. R. Dec. 7, 1938, No. 35716. Convention date, Dec. 8, 1937.. [Class 78 (i)] Material is delivered from the chamber 6 through the outlet 23 to a delivery-pipe 25 by compressed air delivered (1) above the material in the chamber (2) between the pivoted flap 31 and the bottom wall of the chamber ; vibrating the screen in the process and (3) into the delivery-pipe through the conduit 30. All the air-pipes pass through a single casing 37a and the flow is controlled by a single valve. The chamber 6 is supplied at intervals through a sliding gate 7 operated by a ram 8. Three sides of this gate have down wardly and inwardly projecting flanges which project under the outwardlyflanged neck 11 of the chamber, so that when the gate is lifted bodily by the pressure in the chamber the flanges abut against a gasket on the underside of the neck flange and form an airtight seal. The fourth wall abuts a gasket 14 in both the raised and lowered position. The perforated pipe 13 serves to admit air to the interior of the chamber and also to sweep the flanges of the valve and neck clear of adherent material. A water spray may be passed through these perforations at times to assist this latter action. Should the material jam in the outlet 23, the pressure in the conduit 34 builds up and raises the pivoted flap 31, thus allowing a greater discharge of air at the point 39 to remove the obstruction. Also, any variation of pressure in the chamber 6 causes a corresponding variation in the conduit 34 thus causing the flap to vibrate. A door 40 permits access to interior when necessary. In one modification, the flap 31 is not pivoted but is made of thin metal sufficiently resilient to vibrate in response to the change in air-pressure. In a second modification, a pivoted plate is swung hydraulically to sweep the portion of the chamber remote from the outlet, so as to facilitate complete discharge ; the air-pressure arrangements being as previously described.

Title: Production of n-(hydrocarbon substituted) aminocarboxylic acids, their esters or salts
Inventor: REPPE WALTER
Filed: 1956-11-22
Abstract: The invention comprises reacting an aminocarboxylic acid, its esters with a monohydric aliphatic, cycloaliphatic or araliphatic alcohol, or its salts with alkali or alkaline earth metals such compounds containing at least one hydrogen attached to nitrogen, with CO, an olefinic hydrocarbon and water at room temperature or above and increased pressure, in the presence of iron or cobalt carbonyl or carbonyl hydride or an ammonium or amine salt, especially tertiary ring-combined amine salts, of such carbonyl hydrides, to produce N-(hydrocarbon substituted) aminocarboxylic acids, esters or salts, the molar ratio of CO to olefine being 2:1 to 5:1, preferably 3:1. The preferred temperatures and pressures are 80-160 DEG  C. and 5-500 atmospheres, more preferably 10-200 atmospheres, and the preferred catalyst is iron pentacarbonyl. Suitable amino carboxylic acids include aliphatic monobasic acids with 2 to 6 C atoms, such as glycocoll, a -alanine, serine, valine and leucine; aliphatic dibasic acids such as glutamic and aspartic acids; acids containing two amino groups, such as ornithine and lysine; heterocyclic acids such as proline and hydroxyproline; aromatic acids, such as aminobenzoic, N - methylaminobenzoic, N - ethylaminobenzoic and aminonaphthoic acids. Suitable olefinic hydrocarbons include open chain monounsaturated olefines such as ethylene, propylene, n-butylene, iso-butylene, octylene, dodecylene, octadecylene; cyclic olefines such as cyclohexene and cyclo-octene; araliphatic olefines such as styrene; and diolefines such as butadiene, isoprene, dimethylbutadiene, hexanediene-(2,5) and piperylene.  The addition of solvents, such as alcohols, hydrocarbons, esters, lactams and carboxylic acid amides is advantageous; in particular when reacting aminocarboxylic acid esters, it is advantageous to use the alcohol which constitutes the alcoholic component of the esters. The reaction is preferably carried out at alkaline pH, but may be carried out at neutral or slightly acid pH; in this last case the use of formic acid is preferred.  The process may be continuous or discontinuous.  Examples describe the reaction of a -alanine with ethylene, leucine with ethylene, d,l-proline with ethylene, p-aminobenzoic acid ethyl ester with propylene, anthranilic acid with ethylene and 3-amino-2-naphthoic acid with ethylene.  The products are N-substituted by a group containing one carbon atom more than the olefine.
